About Me
Dr. Jerrilyn Johnston has been practicing in the Hayward/Castro Valley area since she completed her residency at Children's Hospital Oakland. She received her medical degree at the University of Utah and is a board-certified pediatrician.
Dr. Johnston loves helping babies and children. Having practiced for over 30 years, she considers it a privilege to take care of families - in some cases for generations. She really enjoys teaching and doing everything she can to be sure her patients receive the best care. Through her daughter's nonprofit, she has seen thousands of patients in rural Guatemala for over a decade. Dr. J., as her patients affectionally call her, enjoys cooking, reading, learning new things and spending time with her husband and children.
